Fusible toy bead and method for producing fusible toy bead

Abstract

A fusible toy bead includes a water-soluble resin and two or more pigments as coloring agents, the water-soluble resin includes polyvinyl alcohol as a main component, and includes 3% by weight of polypropylene, and two or more colors appear on a surface in a mixed manner without intermixing with each other.

What is claimed is: 
     
         1 . A fusible toy bead comprising:
 a water-soluble resin; and   two or more pigments as coloring agents,
 wherein the water-soluble resin comprises polyvinyl alcohol as a main component, and comprises 3% by weight of polypropylene, and 
 wherein two or more colors appear on a surface in a mixed manner without intermixing with each other. 
   
     
     
         2 . A method for producing a fusible toy bead comprising:
 preparing a water-soluble resin comprising polyvinyl alcohol as a main component and 3% by weight of polypropylene;
 dividing the water-soluble resin into two or more parts and mixing each of two or more pigments of different colors into each of the parts of the resin to form two or more types of colored pellets having different colors; and 
 injection molding the two or more types of colored pellets with a mold, while mixing the two or more types of colored pellets. 
   
     
     
         3 . The method for producing a fusible toy bead according to  claim 2 ,
 wherein in the injection molding, the mold has a length of a spool portion of 30 mm or more and 40 mm or less.   
     
     
         4 . The method for producing a fusible toy bead according to  claim 2 ,
 wherein in the injection molding, the mold has a larger diameter of a distal end portion at a runner portion than a diameter of the other portion at the runner portion.   
     
     
         5 . The method for producing a fusible toy bead according to  claim 2 ,
 wherein in the injection molding, the mold has a diameter of a gate portion of 20% or more and 30% or less with respect to a diameter of the fusible toy bead.   
     
     
         6 . The method for producing a fusible toy bead according to  claim 2 ,
 wherein the injection molding is performed at a temperature of 145° C. to 165° C.
